Remember that any forum with a decent amount of visitors will be moderated by people who want to keep spammers out. This may be a surprise to you, but if you're trying to drum up business by posting links to your veterinarian website in inappropriate places, you have just become a spammer. Because moderators want to preserve their forum quality, you'll be quickly banned if you act over promotional.
Some forums will let you have a "signature" part on the bottom of each post. In your signature, you can post a link to your veterinarian website, and it's not considered spam. There are forums that will require a minimum post count before you can post links, and this isn't a bad thing. You'll just have to make sure the forum is a place worth investing your time in.
As for what you put in the body of your posts, you will want to be a source of good information, as well as a pleasant conversationalist. Err on the side of being too relaxed vs. being too pushy in selling your vet services. The more you post, the more you can organically bring up your clinic as a subject of conversation. This requires some patience, but it is worth it.
When promoting your veterinarian website, it's easy to fall into the temptation of posting your URL in every possible location. One might assume forums are the easiest place to do this, but you do need to put some thought into how you post.
